tuned liquid damper, Building Design, Seismic Zone.Abstract
Tuned liquid dampers (TLDs) have been used as passive or semi-active control devices in a wide range of applications, such as tall buildings and high-rise structures. TLDs are passive energy absorbing devices that have been suggested for controlling vibrations of structures under different dynamic loading conditions. This paper is focused on the study of an earthquake protection system, the tuned liquid damper (TLD), which can, if adequately designed, reduce earthquake demands on buildings. A series of experimental tests have been conducted on a scaled model of structure tuned liquid damper systems to evaluate their performance under harmonic excitation. It has been found that with the help of TLD one can resist the structure from lateral failure by 37.4 % which is necessary for the structure to be in its permissible limit.
